Combat Machine is an Android game where you have to clear a lot of obstacles in order to survive. As you play, you will be able to encounter a ton of enemies but you can also receive various roles and weapons as you defeat them, which you can then upgrade as you progress through the game. Some of the weapons include swords, sickles, bows, and more.

The controls are very easy to learn and you will be able to figure them out in no time. It’s a game that’s a perfect choice to pass the time on slow, boring days.
